Report component - The control is overlapped

Hi guys,

I need to create a pie chart on a report component (under dashboard), but this pie chart has the particularity that, instead of showing up the labels of the data presented in the chart itself, i need to show the Total Amount inside the pie. The achieve this, i wanted to add an XF label taking the total from the cube, but  when i set the label over the chart then i have the error "The control is overlapped". 

Do you have any workaround / solution to allow the controls, in particular the labels, overriding a chart?

note: ok under preview that works, but at the end i need to use this report component in a docx file (with narrative reporting) - that's blocking me to use the report.

Thanks a lot in advance,

Regards,

Florence
